This book was released on 2013-08-07 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2011 in the subject Physics - Quantum Physics, Shahjalal University of Science and Technology (Department of Physics), course: Nanostructure Physics, language: English, abstract: This book contains a comprehensive account of application of WKB method to pure Physics of nanostructures containing single or symmetric double barrier V(x) in their band model in presence of longitudinal magnetic field applied along x direction. It concentrates on effects on transmission coefficient of single and symmetric double barriers by three dimensional electron gas (3DEG). Analytical expressions for longitudinal magnetic field dependent transmission coefficient of single and symmetric double barrier of general shape are obtained first. These general expressions are then used to obtain analytical expressions of longitudinal magnetic field dependent transmission coefficient of single and symmetric double barriers of many different shapes we encounter in studying nanostructure Physics. This is followed by thorough numerical investigation to bring out effects of longitudinal magnetic field on transmission coefficient of all these barriers. Comparisons with standard results where available showed excellent agreements. Results of numerical investigation have been explained completely. The book makes well documented, with thorough calculation and discussion, pure Physics of semiconductor nanostructures.

Book Synopsis Nanostructure Physics of Isolated Quantum Well by : Saumitra Singha Dash
Download or read book Nanostructure Physics of Isolated Quantum Well written by Saumitra Singha Dash and published by LAP Lambert Academic Publishing. This book was released on 2010-06 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have studied Physics of a Nanostructure called Quantum Well (QW). We have numerically calculated confined energy levels of electrons, light holes and heavy holes in isolated GaAs-AlGaAs QWs of various widths and depths. We have presented both graphically as well as in the form of data tables variation of the energy levels as width and depth of QW are varied. We find that the values and variations of energy are exactly the same as the values and variations of energy of resonant transmission peaks of symmetric rectangular double barrier. Surprisingly, this is exact numerical agreement. The agreement remains exact even if we take effects of effective mass inequality into account. The book is self-contained; it contains necessary Nanostructure Physics, Microelectronics, Quantum Mechanics, as well as results for symmetric rectangular double barrier for ready reference. Interested reader will be able to assimilate the book completely.

This book was released on 2010-06 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have demonstrated Physics for which we need to modify boundary condition to be used in matching solutions of Schroedinger equation at finite potential discontinuities i.e. at interfaces between barrier and quantum well materials, because of difference of effective mass of electron in their conduction bands. Using the modified boundary condition, we have presented thorough and complete analytical calculation of transmission coefficient of nanostructures called single rectangular tunnel barrier and symmetric rectangular double barrier. We have presented numerical investigations for the two nanostructures. We find that parametric dependences of energy of resonant transmission peaks of the double barrier do not change qualitatively because of taking effective mass inequality into account; but we find changes in energy and in full width at half maxima (FWHM) of the resonant peaks. The book is self contained; it contains necessary Nanostructure Physics, Microelectronics and Quantum Mechanics to enable interested reader assimilate the book completely.

The most wonderful feature is its efficient style of exposition ... an excellent book." Physics Today "Presents the theoretical derivations carefully and in detail and gives thorough discussions of the experimental results it presents. This makes it an excellent textbook both for learners and for more experienced researchers wishing to check facts. I have enjoyed reading it and strongly recommend it as a text for anyone working with semiconductors ... I know of no better text ... I am sure most semiconductor physicists will find this book useful and I recommend it to them."
